Genome sequencing shows climate barrier to spread of Africanized bees

A wild honeybee in Davis, California. European honeybees (Apis mellifera) were introduced to the Americas in the 1600s. Since 1957, "Africanized" honeybees (Apis mellifera scutellata) have interbred with other honeybees. New genomics research shows that ....

A flexible color-changing film inspired by chameleon skin

Credit: CC0 Public Domain Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays, but ....

Captive-bred salmon in wild may do more harm than good

On average, salmon reared in hatcheries in Ireland's Burrishoole catchment only produced a third as many offspring in the North Atlantic compared to wild fish Releasing captive-bred Atlantic salmon into the ocean, a long-standing practice ....
